8243b7f5dc regmap: Updates for v3.12
A quiet release for regmap, some cleanups, fixes and:
 
  - Improved node coalescing for rbtree, reducing memory usage and
    improving performance during syncs.
  - Support for registering multiple register patches.
  - A quirk for handling interrupts that need to be clear when masked
    in regmap-irq.

248d296d6d SCSI fixes on 20130831
This is a bug fix for the pm80xx driver.  It turns out that when the new
 hardware support was added in 3.10 the IO command size was kept at the old
 hard coded value.  This means that the driver attaches to some new cards and
 then simply hangs the system.

Pull networking fixes from David Miller:

 1) There was a simplification in the ipv6 ndisc packet sending
    attempted here, which avoided using memory accounting on the
    per-netns ndisc socket for sending NDISC packets.  It did fix some
    important issues, but it causes regressions so it gets reverted here
    too.  Specifically, the problem with this change is that the IPV6
    output path really depends upon there being a valid skb->sk
    attached.

    The reason we want to do this change in some form when we figure out
    how to do it right, is that if a device goes down the ndisc_sk
    socket send queue will fill up and block NDISC packets that we want
    to send to other devices too.  That's really bad behavior.

    Hopefully Thomas can come up with a better version of this change.

 2) Fix a severe TCP performance regression by reverting a change made
    to dev_pick_tx() quite some time ago.  From Eric Dumazet.

 3) TIPC returns wrongly signed error codes, fix from Erik Hugne.

 4) Fix OOPS when doing IPSEC over ipv4 tunnels due to orphaning the
    skb->sk too early.  Fix from Li Hongjun.

 5) RAW ipv4 sockets can use the wrong routing key during lookup, from
    Chris Clark.

 6) Similar to #1 revert an older change that tried to use plain
    alloc_skb() for SYN/ACK TCP packets, this broke the netfilter owner
    mark which needs to see the skb->sk for such frames.  From Phil
    Oester.

 7) BNX2x driver bug fixes from Ariel Elior and Yuval Mintz,
    specifically in the handling of virtual functions.

 8) IPSEC path error propagations to sockets is not done properly when
    we have v4 in v6, and v6 in v4 type rules.  Fix from Hannes Frederic
    Sowa.

 9) Fix missing channel context release in mac80211, from Johannes Berg.

10) Fix network namespace handing wrt.  SCM_RIGHTS, from Andy
    Lutomirski.

11) Fix usage of bogus NAPI weight in jme, netxen, and ps3_gelic
    drivers.  From Michal Schmidt.

12) Hopefully a complete and correct fix for the genetlink dump locking
    and module reference counting.  From Pravin B Shelar.

13) sk_busy_loop() must do a cpu_relax(), from Eliezer Tamir.

14) Fix handling of timestamp offset when restoring a snapshotted TCP
    socket.  From Andrew Vagin.

0affdf347f net: fec: fix time stamping logic after napi conversion
Commit dc975382 "net: fec: add napi support to improve proformance"
converted the fec driver to the napi model. However, that commit
forgot to remove the call to skb_defer_rx_timestamp which is only
needed in non-napi drivers.

(The function napi_gro_receive eventually calls netif_receive_skb,
which in turn calls skb_defer_rx_timestamp.)

This patch should also be applied to the 3.9 and 3.10 kernels.

29eb51a728 irqchip: sirf: move from legacy mode to linear irqdomain
the series of patches for irqdomain core in 3.11 has broken sirf
irq which uses legacy mapping. all users fail in the new kernel
while setupping irq.

this patch moves to linear irqdomain and drop old legacy irqdomain
codes since we don't need it any more, and at the same time, it
also fixes the broken interrupts of sirfsoc in 3.11.

on the other hand, we actually only have 64 interrupt sources for
prima2 and atlas6, but there are 128 interrupt souces for marco
which uses GIC. in the legacy codes, sirf gpio also uses legacy
irqdomain, so to make gpio interrupt mapping not depend on the
prima2/atlas6/marco an use unified marco,we enlarge prima2/atlas6
interrupt number to 128. here we don't need this workaround any
more as sirf gpio also moved to linear mode before. so we move
SIRFSOC_NUM_IRQS back to 64 too.

3f4ff561bc regmap: rbtree: Make cache_present bitmap per node
With devices which have a dense and small register map but placed at a large
offset the global cache_present bitmap imposes a huge memory overhead. Making
the cache_present per rbtree node avoids the issue and easily reduces the memory
footprint by a factor of ten. For devices with a more sparse map or without a
large base register offset the memory usage might increase slightly by a few
bytes, but not significantly. E.g. for a device which has ~50 registers at
offset 0x4000 the memory footprint of the register cache goes down form 2496
bytes to 175 bytes.

Moving the bitmap to a per node basis means that the handling of the bitmap is
now cache implementation specific and can no longer be managed by the core. The
regcache_sync_block() function is extended by a additional parameter so that the
cache implementation can tell the core which registers in the block are set and
which are not. The parameter is optional and if NULL the core assumes that all
registers are set. The rbtree cache also needs to implement its own drop
callback instead of relying on the core to handle this.

472fdec738 regmap: rbtree: Reduce number of nodes, take 2
Support for reducing the number of nodes and memory consumption of the rbtree
cache by allowing for small unused holes in the node's register cache block was
initially added in commit 0c7ed856 ("regmap: Cut down on the average # of nodes
in the rbtree cache"). But the commit had problems and so its effect was
reverted again in commit 4e67fb5 ("regmap: rbtree: Fix overlapping rbnodes.").
This patch brings the feature back of reducing the average number of nodes,
which will speedup node look-up, while at the same time also reducing the memory
usage of the rbtree cache. This patch takes a slightly different approach than
the original patch though. It modifies the adjacent node look-up to not only
consider nodes that are just one to the left or the right of the register but
any node that falls in a certain range around the register. The range is
calculated based on how much memory it would take to allocate a new node
compared to how much memory it takes adding a set of unused registers to an
existing node. E.g. if a node takes up 24 bytes and each register in a block
uses 1 byte the range will be from the register address - 24 to the register
address + 24. If we find a node that falls within this range it is cheaper or as
expensive to add the register to the existing node and have a couple of unused
registers in the node's cache compared to allocating a new node.

194c753a21 regmap: rbtree: Simplify adjacent node look-up
A register which is adjacent to a node will either be left to the first
register or right to the last register. It will not be within the node's range,
so there is no point in checking for each register cached by the node whether
the new register is next to it. It is sufficient to check whether the register
comes before the first register or after the last register of the node.

21ea9f5ace drivers/base/memory.c: fix show_mem_removable() to handle missing sections
"cat /sys/devices/system/memory/memory*/removable" crashed the system.

The problem is that show_mem_removable() is passing a
bad pfn to is_mem_section_removable(), which causes

    if (!node_online(page_to_nid(page)))

to blow up.  Why is it passing in a bad pfn?

The reason is that show_mem_removable() will loop sections_per_block
times.  sections_per_block is 16, but mem->section_count is 8,
indicating holes in this memory block.  Checking that the memory section
is present before checking to see if the memory section is removable
fixes the problem.

03803a59e3 net: usb: Add HP hs2434 device to ZLP exception table
This patch adds another entry (HP hs2434 Mobile Broadband) to the list
of exceptional devices that require a zero length packet in order to
function properly. This list was added in commit 844e88f0. The hs2434
is manufactured by Sierra Wireless, who also produces the MC7710,
which the ZLP exception list was created for in the first place. So
hopefully it is just this one producer's devices that will need this
workaround.

Tested on a DM1-4310NR HP notebook, which does not function without this
change.

26ee47411a regmap: debugfs: Fix continued read from registers file
The regmap_debugfs_get_dump_start() function maps from a file offset to the
register that can be found at that position in the file. This is done using a
look-up table. Commit d6814a7d ("regmap: debugfs: Suppress cache for partial
register files") added a check to bypass the look-up table for partial register
files, since the offsets in that table are only correct for the full register
file. The check incorrectly uses the file offset instead of the register base
address and returns it. This will cause the file offset to be interpreted as a
register address which will result in a incorrect output from the registers file
for all reads except at position 0.

The issue can easily be reproduced by doing small reads the registers file, e.g.
`dd if=registers bs=10 count=5`.

34d5626afc bnx2x: Fix move FP memory deallocations
If driver will fail to allocate all queues, it will shrink the number of
queues and move the storage queue to its correct place (i.e., the last
queue among the newly supported number).

When changing the pointers of the new location of the FCoE queue, we need
to pay special attention to the aggregations pointer - that memory is allocated
during probe and released upon driver removal. Current implementation has 2
pointers pointing to the same chunk of allocated memory, meaning upon removal
there will be two kfree() of the same chunk while the other won't be released.

This is one more set of fixes intended for the 3.11 stream...

For the mac80211 bits, Johannes says:

"I have three more patches for the 3.11 stream: Felix's fix for the
fairly visible brcmsmac crash, a fix from Simon for an IBSS join bug I
found and a fix for a channel context bug in IBSS I'd introduced."

Along with those...

Sujith Manoharan makes a minor change to not use a PLL hang workaroun
for AR9550.  This one-liner fixes a couple of bugs reported in the Red Hat
bugzilla.

Helmut Schaa addresses an ath9k_htc bug that mangles frame headers
during Tx.  This fix is small, tested by the bug reported and isolated
to ath9k_htc.

Stanislaw Gruszka reverts a recent iwl4965 change that broke rfkill

    but it's non-invasive which we need for this late in the release

  - Add another header used in the !CONFIG_REGMAP stubs where we had been

assume that reg_stride is 1. This will break the rb cache for configurations

This solves a problem observed in kexec'ed kernel where 200ms timeout is
too short and bootconsole fails to initialize. Console did eventually
become workable but much later into the boot process.

Observed timeout was around 260ms, but I decided to make it a little bigger
for more reliability.

This has been tested on Power7 machine with Petitboot as a primary
bootloader and PowerNV firmware.

The IO command size is 128 bytes for these new controllers as opposed to 64
for the old 8001 controller.

The Adaptec out-of-tree driver did this correctly. After comparing the two
this turned out to be the crucial difference.

So don't hardcode the IO command size, instead use pm8001_ha->iomb_size as
that is the correct value for both old and new controllers.
